Bandit tend to attack together. In packs, if you will. Like hyenas. They mostly go after large groups and then fight for the spoils among themselves.

Don't really see Nate rolling with groups. He's more of a solitary creature. Like a leopard. He'll stalk along the highway alone looking for anything that piques his interest and then pounce if he thinks he can take them. At most, he'll have a partner or a patsy to keep him company but he wouldn't work with a group for any extended period of time.
